Description

The invention relates to a water deflector for arrangement in front of a windshield of a motor vehicle.

A water deflector serves to protect an area between a hood and the windshield from dirt and water. Windscreen wipers are often placed directly on the water deflector. The windscreen wipers may be in a rest position either on the windshield or on a windshield connection area.

At currently usual, in 1 illustrated water deflectors 101 are immediately adjacent to the windscreen wiper 102 in an intermediate area 103 between the windscreen wiper 102 and a hood 104 surveys 105 arranged. The windshield wiper 101 pushes snow and ice in appropriate weather conditions. This allows under the wiper 101 Snow and ice are deferred and stowed. It can be in one area 106 between the windscreen wiper 101 and the surveys 105 on the water deflector damming a snow wedge, which can lead to the windshield wiper 102 a normal position or a rest position N can not reach. This may cause a windshield wiper 102 actuating mechanism to be stressed. In addition, caused by the impact of the windshield wiper 102 on the dammed snow disturbing noise, which can penetrate into the interior of the vehicle.

From the DE 42 35 114 A1 In addition, a cowl for a motor vehicle for receiving at least one windshield wiper in a parking position is known. The cowl has a heating device which defrosts snow and ice by the action of heat.

An object of the invention is to provide a water deflector in which snow can not accumulate or at least the accumulation of snow is at least reduced.

This object is solved by the features of patent claim 1. Further advantageous embodiments of the invention are each the subject of the dependent claims. These can be combined in a technologically meaningful way. The description, in particular in conjunction with the drawing, additionally characterizes and specifies the invention.

• – einen angrenzend an die Windschutzscheibe und eine flächige Fortsetzung der Windschutzscheibe bildenden Windschutzscheiben-Anschlussbereich,
• – einen Motorhauben-Anschlussbereich, sowie
• – einen sphärisch gekrümmten Ablaufbereich, welcher sich in einer Fahrzeugquerrichtung mindestens über einen an die Scheibenwischer angrenzenden Bereich und in einer Fahrzeuglängsachse von dem Windschutzscheiben-Anschlussbereich bis zu dem Motorhauben-Anschlussbereich erstreckt.

Accordingly, a water deflector is provided, which can be arranged between a windshield and an engine hood of a motor vehicle, wherein the motor vehicle has a windshield wiper, wherein the water deflector comprises:

• A windshield connection area adjacent to the windshield and a flat continuation of the windshield,
• - A hood connection area, as well
• A spherically curved discharge region which extends in a vehicle transverse direction at least over an area adjoining the windscreen wiper and in a vehicle longitudinal axis from the windshield connection region to the engine hood connection region.

On the closed surface, snow and ice can easily slide off the windshield wiper and be easily pushed away by the windshield wiper. By no such surveys are provided in the intermediate region between the windscreen wiper and the hood, no snow wedge can be dammed up.

According to an advantageous embodiment, an angle between the windshield connection area and the outlet area is greater than 120 °, in particular greater than 130 °, particularly preferably greater than 140 °. The angle is due to the fact that the windshield is arranged inclined with respect to the vehicle longitudinal axis to the rear and the water deflector must compensate for the inclination of the windshield as a transition part between the windshield and the hood. By choosing a relatively obtuse angle to compensate for the inclination of the windshield, the snow can be more easily pushed from the windshield wiper to the drain area via the windshield connection area.

According to one embodiment, the windshield connection region merges into the drainage region in a rounding region with a radius of 5 mm to 50 mm, in particular of 10 mm to 40 mm. By means of a corresponding rounding area, the windshield wipers can more easily push the snow onto the drainage area. This can avoid that the snow gets caught in the edge even before the drainage area and dammed up as a snow wedge.

According to a further advantageous embodiment, the drainage area has at least one air inlet in peripheral areas. As a result, air can be sucked in for a ventilation of the interior in a manner known per se, and the water deflector can divert water in peripheral areas.

According to an advantageous embodiment, the at least one air inlet in the vehicle transverse direction is arranged outside a region adjacent to the windshield wipers in the vehicle longitudinal direction. The area adjacent to the windshield wipers in the vehicle longitudinal direction is the area in which the windshield wiper can push snow in its downward movement. By no air outlets are arranged here, it can be avoided that the windshield wiper pushes snow over the air inlets during operation and forms a snow wedge here.

According to a further embodiment, the hood connecting region is arranged at a distance of at most 15 mm, in particular at most 10 mm, particularly preferably at most 5 mm, from a hood edge. This creates a narrow transition between the bonnet and the water deflector. Snow can not accumulate on a narrow transition.

An exemplary embodiment will be explained in more detail below with reference to the drawing. Show it:

1 FIG. 2 schematically shows, in a sectional view, a water deflector with an elevation on which a snow wedge can form, FIG.

2 FIG. 2 schematically shows, in a sectional view, a water deflector with a drainage area on which no snow wedge can slide on, and FIG

3 in a perspective view schematically a part of a vehicle with a windshield, swivel windscreen wipers and a hood and a arranged between the windshield and the hood water deflector.

In the figures, identical or functionally identical components are provided with the same reference numerals.

1 shows a known water deflector 101 of the type described above. Between a windshield wiper 102 and a survey 105 If necessary, an unillustrated snow wedge can be pushed on. The snow may have accumulated there before the ride and while driving through the windscreen wiper 102 can add more snow to the intermediate area 103 be pushed. This can be one in the survey 105 arranged air inlet 106 be clogged. Furthermore, a drive mechanism, not shown, which the windshield wiper 102 operated, be exposed by the snow wedge increased loads.

To prevent this is at the water deflector 201 , according to the 2 and 3 no such survey provided.
